Device for the Storage and Treatment of Biodegradable Wet Solid Waste

Abstract

The present invention relates to a device for the storage and treatment of biodegradable wet solid waste, especially for vegetarian household waste materials. The device consists of a bucket shaped container with a mesh bottom and a removable cover with a hole at the center. The container is provided with a leachate collection basket at the bottom, which is mounted on an iron stand to hold the device. Openings are provided on the lateral surface of the basket for ventilation. The waste is added to the container from the top by hand lifting the lid. The ventilation facilitates degradation of the material in side the container, reducing the release of odour and, leachate. The volume of the waste also gets reduced because of self-compaction. In one embodiment the storage and treatment device is provided in the form of a house hold kit.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application claims priority to Indian Patent Application No. 293 / Del / 2007 filed Feb. 14, 2007, which is incorporated herein by reference to the extent not inconsistent herewith.FIELD OF THE INVENTION[0002]The present invention relates to a device for the storage and treatment of biodegradable wet solid waste. In particular, the invention relates to the device for storage and treatment of biodegradable wet solid waste, thus for improving integrated solid waste management system for the biodegradation and recycling of household waste.BACKGROUND[0003]The solid waste management system involves collection, transportation, processing, treatment and disposal of waste generated day to day in the city. The most important part of solid waste management system is the collection of waste. Based on the collection system only other systems viz., transportation, processing, treatment and disposal of waste are decided. Presently, house-to-house colle...

AI Technical Summary

Benefits of technology

[0031]Still another objective of the present is to provide longer period for storage (detention time) of biodegradable wet waste.

[0032]Yet another objective of the present invention is to provide reduction in total cost on collection, segregation, transportation, processing, treatment and disposal of waste, if solid waste management system at urban centers is designed properly.

[0033]Another objective of the present invention is to provide less land requirement for disposal of waste, as there is land scarcity in metropolitan and big cities.

[0034]Still another objective of the present invention is to provide dust bin which occupies very small space for its easy handling and operation to individual houses.

[0035]Yet another objective of the present invention is to design dust bin very attractive so that it can be kept at any place in the house where there is proper air circulation.

Problems solved by technology

The wastes collected by these systems are heterogeneous in nature.

This creates problems and difficulties in treatment and processing of wastes.

It is very difficult to segregate individual components of comingled solid waste for effective treatment and processing.

The problems associated with the management of solid wastes are complex because of the quantity and diverse nature of the wastes, the rapid development of sprawling urban areas, the funding limitations for public services in many large cities, the impact of technologies and emerging limitations in both energy and raw materials.

Waste generation is, at present, an activity that is not very controllable.

Collection system accounts for almost 50 percent of the total annual cost of urban solid waste management.

This service may cost the individual homeowner Rs.

Hence the wastes collected in such bins require disposal in community bins every or alternate day and is unavoidable.

The major drawback of all the above-cited bins is that they pose unwanted foul odour.

The household bins without lid or cover pose the problem of insects and flies also.

Moreover, these bins are not suitable for summer, rainy and winter seasons.

Until now no household dust bin for the storage of biodegradable wet waste has been patented.

Such storage bins can be located on a ground site or in the hold of a ship and does not address the existing problems.

The bin is made up of a biodegradable material which is organic membrane and does not address the existing problems.

Unfortunately, these prior art devices possess inherent deficiencies like unsuitable size, difficult to operate and high cost.

These patents do not address the existing problems.

The problem of foul odour, insects and flies is caused due to the formation of leachate as a result of the decomposition of waste.
